' In Palestine May 26, 1946 Section 1, Public Law 690, August 8, 1946 Patent expires May 26, 1966 2 Claims. (015-11) The present invention relates to auxiliary beds of the type adapted to be placed underneath a higher bed or couch when not in use, and which can be raised to the height of the higher bed and placed beside it, to afiord additional sleeping accommodation.

Various constructions are known to enable the raising of such beds, such as telescoping legs, auxiliary legs which can be folded or swung inward, and the like more.

According to the invention the auxiliary bed is provided with two superimposed rectangular frames. The lower frame has attached to it fixedly legs of ordinary construction, made from metal tubes, or angle iron or the like, while the upper frame constitutes the bedspring, being provided with the usual springy steel bands, chains or the like, and serves as support for the hair mattress.

The upper frame is connected with the lower one by two pairs of levers arranged at two opposite sides of the bed, each lever being pivoted with its lower end to the lower frame, and its upper end being bent horizontally towards the middle of the bed, said bent ends engaging slidingly in oblong guides provided on the underside of the upper frame, each two oppositely disposed levers being interconnected by a cross bar.

The invention will now be described with reference to the annexed drawing, showing in Fig. 1 a fractional elevational section of the new bed, with the upper frame in raised position, showing the lower position in dotted lines.

Fig. 2 is a fractional section'on line II-II of Fig. l.

Fig. 3 is a diagrammatical sketch of a slightly modified construction.

According to Fig. 1, a rectangular frame 2 made from angle iron is supported by legs I. On the two longer sides of the frame, near the head and foot ends of the bed, are arranged upright lugs 3, in which are pivoted levers 4. The upper ends of levers 4 are bent inwardly, as seen in Fig. 2 to form supports for a frame 5 in which are arranged the usual steel bands 6.

Two opposite levers 4 are connected by a cross bar 4' extending above the steel bands so that they can be moved simultaneously, said cross bars serving as handles.- Levers 4 and cross bar 4 form an integral rod shaped like an inverted U.

The paths of the swinging movement of levers 4 are limited by stirrups 8, fixed to the lower side of frame 5, to form guides for the inwardly bent portions of the levers. A sleeve "I is slid on each bent portion to decrease friction in the guides. Horizontal pins 3 in the lower frame 2 serve as abutments for levers d.

It will be seen that on swinging levers 4 from the position indicated by dotted lines in Fig. 1, into that drawn in full lines, the frame 5 will be raised. By swinging the levers inwardly into the lowest position, the upper frame will be brought down onto the lower one.

According to Fig. 3, the two opposite levers at the head of the bed are linked with those at the foot end at approximately their middle by a bar or a pair of rods 9. Thus all four levers can be swung simultaneously and only one pair of opposite levers need be connected by a cross bar 1. In that case, one longitudinal side of the lower frame, the two levers on the same side, and the connecting rod form a bar link chain, with opposite links equal in length.

What I claim is:

1. In a. bed of the type adapted to be placed underneath a higher bed When not in use and which can be raised to the height of the higher bed and placed beside it, to afford additional accommodation, a lower elongated frame having legs fixedly attached thereto, an upper elongated frame being provided with a spring mattress, pairs of levers pivoted at their lower ends within the angles of angle irons forming the lower frame and having each an inwardly bent step near its upper end said steps affording abutments supporting the upper frame in erected position, and an approximately horizontal bar at least at one end of the bed extending across and above the opening of the upper frame and connecting the upper ends of the levers at said one end.

2. A bed as claimed in claim 1, wherein each cross bar and the levers connected thereby form an integral part shaped like an inverted U, the middle or horizontal portion of the U extending over the space between the two parallel longitudinal angle irons of the upper frame.
